ROLL SUPPORT FOR SPINNING AND LIKE MACHINES.

My invention has relation to the roll drawing mechanism of thetype that is customarily used in machines for spinning worsted or silk yarns. In the present construction of machines of this class the stands supporting the drawing rolls are usually cast in one piece as shown in Figure 10 of U. S. Patent No. 765716, July 26, 1904. This construction is objectionable, as difficulty is met making the castings and properly fitting them to the framing of the machine, and furthermore, the expense of replacement in case of breakage is considerable.

In particular my invent-ion relates'to an improved construction of the drawing rolls supporting stands; and the principal object of the invention is to simplify and otherwise improve the structure of said stands where by the expense of fitting to the machine frame and the replacement of broken parts will be reduced to a minimum.

Another object of my invention is to provide means whereby a variation in degrees of the angle of inclination of roll supports may be readily made when desired.

A further object "of my invention is to provide a simple and inexpensive construction of a roll supporting stand whereby the.

amount of space between the front and back drawing rolls may be increased whenever it is desired to operate on a longer length of fibre than the maximum length for which the machine was built.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, 7 it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is fully described in the following specification, illustrated by the accompanying drawings, in which like reference characters designate like parts.

designates one of the end framesof the machine, (the opposite end frame not shown in the drawings), 2 is a beam extending longitudinally at the front of the machine and is fixedly connected to the end frames ofthe same. The beam 2 in combination with the creel board 3 fixed to the top of the machine support a plurality of stands or supports on which the bearings of the drawing rolls, held in suitable holders, are mounted either in a fixed position or slidable thereon. Each stand or support is made up of four separate members or sections, detachably con nected together, comprising a front member 4, a rear member 5, an intermediate member 6 and a base member 11. The upper partof the front member 1 serves as a holder for the bearing 12 of the front roll 13, the lower part of said member being provided with trunnions 7 slidably mounted in a hole or bearing in the web of the member and positioned therein by a set screw 8. These trunnions are swingably in bearings 9 and 10 in the upright lugs integral with the base member 11 which is securely mounted on the rail 2. In a boss let on the rear part of the front member lahole or seat is located in which the front end of the intermediate member 6 is seated and detachably secured therein preferably by the set screw 15.

The intermediate member 6, supporting the bearing slides of the carrier and back rolls, is made preferably of a bar of cold rolled metal of a circular cross section cut in varying lengths thus providing changeable means whereby the space between the front and back rolls-may be increased so that the rolls will properly function on a length of fibre greater than the maximum for which the machine was built. This feature of my improved roll stand or support has met with tans-raids from yam face of the intermediate member 6;

manufacturers as its adoption in place of the old type of one piece roll support results in substantial savings in expenses of new parts and labor required in changing the machine over. 7

The carrier roll bearing slides 16 and the back roll bearing slides 17 are provided with arcuate shaped bases conforming to the curvature of the surface of the intermediate member 6 011 which they are slidably mounted. The positions of the carrier and back rolls may be varied in their relation to each other by means of manually operated shafts 18, extending longitudinally beneath the intermediate member 6, with pinions 19 fixed thereon and coacting with racks 20 cut in the lower sides of said intermediate member. Each carrier roll bearing slide 16 is fastened in its proper position on the intermediate member 6 by means of a screw 21 threaded into a nut 22 slidably mounted in the dovetailed slot 23 cut in the upper sur- Each back roll bearing slide 17 is held in position on the intermediate member by an eye bolt formed with a ring 24-, embracing the intermediate member 6, and a stem 25 which is threaded into a clamping nut 26 coasting with the upper surface of the back roll hearing slide.

The rear member 5 supporting the rear end of the roll stand or support is detacln ablyconne cted to the rear end of the men-- ber 6 preferably by the set screw 27, and is adjustably mounted on a hanger 28 fixedly connected to the creel board 3. The adjusting slot 29 in the hanger 28 is formed on the arc ofa circle concentric with the centre of the trunnions 'Z whereby the proper inclination of the roll support may be obtained; when this is accomplished the member 5 and the hanger 28 are tightly clamped together by the bolt 30 passing through the slot 29 and threaded into the member 5.

By the construction above described, the fitting of the roll supports to the framing of the machine is easily and quickly accom: plished; in case of breakage the expense of replacement is greatly reduced in comparison withthe use of the ordinary type of one piece construction of roll supports, and the machine can be readily adapted to spin varying lengths of fibre by the use of difi'erent lengths of the intermediate member.

It is sometimes found desirable to siinultaneously vary the inclination of all of the roll supportswhich my invention readily accomplishes by means of arcuate racks 31 attached to the support members 5 and cooperating with pinions 32 fixed to a manually operated shaft 33 extending longitudinally beneath the creel board 3. By this construction the operative desiring to change the inclinaion of all of the roll supports, loosens theclamping bolts 30 and twists the shaft 33' one way or the other until the desired inclination is obtained, then retighten the bolts 30. The shaft 83 may be turned by any suitable manually operated means preferably I make use of a gear 34 fixed to shaft 33 and cooperating with a worm '35 manually rotated by a handle on shaft 36.
